There is nothing wrong with owning at Vidanta. However, they will never truly buy your timeshare. It's just a ploy to get you to buy. The key is to get the level/unit you want and to get proper addendums written into the contract. Most who visit for the presentation do not understand that it is a negotiation and you have leverage. You have what they want - your money and signature. First, don't buy in at lower than the Grand Bliss level. If they tell you you can not then tell them you have ZERO interest. Trust me, they will come up with a way that a Grand Bliss level contract is suddenly available. Usually with some story that it just became available from a member who defaulted. It's all BS - EVERYTHING that comes out of the sales person's mouth is BS. Personally I would not enter a Vidanta contract at a level lower than Grand Luxxe. Again, they will try to tell you it's not available. Trust me, it is.
What you want is a typical Vidanta 1+ 2 contract. It is a registered week that is good for 10 years and 2 right to use contracts that are good for 100 years (renewable every 10 years). You want the Golf and Spa privileges. They used to offer 16 free round of golf and 2 free massages per week. Now it's $40/$60 golf and 2 for 1 massage. Push to get the former if you can. Next you want an addendum that gives you access to 100% of the available inventory up to 12 months in advance for all 3 week. This is very important. Next you want an addendum that you do not pay mandatory maintenance fees. This is easy to get and most of the time is offered up front. Most importantly, you want an addendum that states that if you sell your contract the transfer fee will be no more than the taxes originally paid for the contract. Otherwise, your Grand Luxxe contract will state that the transfer fee is 10x your usage fee. This will make the transfer fee somewhere between $18,000 - $48,000 depending on the unit you buy into. Taxes will only be between $2,800 - $5,000. You also want an addendum in writing that states all of your privileges will be available to your guests if you are not present at the resort. For example, if you let a friend, relative or renter use one of your weeks, Vidanta will not allow them to have any of your privileges because you are not there using the unit. This is a key addendum that you should demand and refuse to buy without it.
The theme park in Nuevo Nayarit is currently in a soft opening. I should be fully opened with the next 10 - 12 months. Be sure to get the VIP park package and gondola privileges included in your contract. It allows you VIP access to all of their parks, present and future. You can pay for 1.5 days at the park and get 7 days. Currently they have the Jungala water park in Riviera Maya and the theme park in Nuevo Nayarit. They are talking about building a theme park in Riviera Maya and they can do it as they have a very expansive amount of land across the highway where their Cirque Du Soliel show is. They are also building a larger Jungala water park at the Nuevo theme park that will be part of phase 2 across the highway. So the VIP package is going to be important.
Understand that the Vidanta sales people will lie to you and promise things that do not exist. Anything you are interested in, tell them to put it in writing. It will shut them up... Also, they will start with prices that are higher than a mansion here in the US. When they do, please laugh out loud at them. Make them uncomfortable - it will only help your cause. For Grand Luxxe your contract should be around this price: Grand Luxxe - Master Room (studio) $12,000, Junior Suite (small 1 bedroom) $16,000, Grand Luxxe Loft (studio) $19,000, 1 bedroom suite $22,000, 1 bedroom villa $22,000, 2 bedroom suite $30,000, 2 bedroom villa $33,000, 2 bedroom spa $30,000, 3 bedroom spa $38,000, 1 bedroom residence loft $58,000, 2 bedroom residence loft $79,000, 3 bedroom residence loft $99,000, 2 bedroom residence (in construction) $79,000, 3 bedroom residence (in construction) $105,000, 4 bedroom residence $160,000. Estates - 1 bedroom $150,000, 2 bedroom $210,000, 3 bedroom $275,000, 4 bedroom $500,000+. Empire estates will cost a little more than the Estates in the same unit sizes.
